As the name suggests, it is a mechanical device for the fine rolling of aluminum sheets. It is mainly used to further roll rough-rolled aluminum sheets or intermediate billets into aluminum products of the required thickness, size, and shape. This rolling method can significantly improve the density, strength, and surface quality of aluminum materials, meeting the production requirements of high-precision aluminum products. The working principle of the precision aluminum sheet rolling mill is mainly to roll the aluminum sheet using two or more relatively rotating rolls. Precision aluminum sheet rolling mills are mainly suitable for industries that require high-precision aluminum products, such as aerospace, high-speed rail, and automobile manufacturing.
[0003] In existing technologies, the rolling oil used in the rolling process of existing finishing mills drips onto the surface of the sheet as the rolls rotate.

This residue can contaminate the sheet surface, leading to a decrease in product surface quality. Furthermore, in subsequent processing or treatment, this grease can increase surface roughness and reduce smoothness, thus affecting the quality and appearance of the final product. Therefore, it is necessary to improve the aluminum sheet processing finishing mill to solve the above problems. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figure 1 - Figure 5This utility model provides an embodiment of an aluminum sheet processing precision rolling mill, including a worktable 1, a base plate 21, and an adjustment assembly. A feeding device 4 is fixedly connected to the top of the worktable 1, a precision rolling device 5 is fixedly connected to the top of the worktable 1, and a flattening device 6 is fixedly connected to the top of the worktable 1. An adjustment assembly for adjusting the height of the worktable 1 is provided at the bottom of the worktable 1. The base plate 21 is fixedly connected to the top of the worktable 1, a protrusion 22 is fixedly connected to the top of the base plate 21, a first V-shaped hanging strip 25 is fixedly connected to the top of the protrusion 22, a limiting shaft 23 is fixedly connected to the top of the base plate 21, an adjusting plate 210 is slidably connected to the outside of the limiting shaft 23, and an optical shaft 213 is slidably connected to the inside of the adjusting plate 210. The optical shaft 213 is fixedly connected to the outside of... A limit plate 214 and an optical axis 213 are fixedly connected to a movable plate 215 at their bottom. A spring 216 is fixedly connected between the movable plate 215 and the adjusting plate 210. A second V-shaped hanging strip 217 is fixedly connected to the bottom of the movable plate 215. The elasticity of the spring 216 causes the second V-shaped hanging strip 217 fixedly connected to the bottom of the movable plate 215 to press against the aluminum sheet, pressing the aluminum sheet between the first V-shaped hanging strip 25 and the second V-shaped hanging strip 217. The second V-shaped hanging strip 217 guides the rolling oil on the aluminum sheet to both sides, thereby cleaning the aluminum sheet. This effectively removes the rolling oil from the sheet, improving the surface quality of the product, increasing its surface roughness and smoothness, and ultimately improving the quality and appearance of the final product. This also enhances the suitability of the device. To improve responsiveness and usability, when the height of the worktable 1 needs adjustment, the adjustment component rotates knob 35 to unscrew the second threaded rod 34 from the threaded hole of the support rod 31. Activating the hydraulic telescopic rod 38 adjusts the height of the worktable 1, aligning the threaded hole of the support rod 31 with the corresponding round hole 36, allowing the second threaded rod 34 to be inserted into the round hole 36. Reversing the rotation of knob 35 connects the second threaded rod 34 to the threaded hole of the support rod 31, supporting the worktable 1 and improving its usability. Four sets of first V-shaped hanging bars 25 are provided, distributed from left to right on the top of the base plate 21. These bars are supported by the spring 216. The second V-shaped hanging strip 217, fixedly connected to the bottom of the movable plate 215, presses the aluminum sheet between the first V-shaped hanging strip 25 and the second V-shaped hanging strip 217. The second V-shaped hanging strip 217 guides the rolling oil on the aluminum sheet to both sides, thus cleaning the aluminum sheet. Four sets of the second V-shaped hanging strip 217 are arranged from left to right at the bottom of the movable plate 215. The spring 216's own elasticity presses the second V-shaped hanging strip 217 fixedly connected to the bottom of the movable plate 215 between the aluminum sheet and the first V-shaped hanging strip 25 and the second V-shaped hanging strip 217, thus guiding the rolling oil on the aluminum sheet to both sides, thereby cleaning the aluminum sheet.Several optical axes 213, springs 216, and limiting discs 214 are provided, symmetrically distributed inside the adjusting plate 210. The springs 216, through their own elasticity, press the second V-shaped hanging strip 217, fixedly connected to the bottom of the movable plate 215, against the aluminum sheet, pressing the aluminum sheet between the first V-shaped hanging strip 25 and the second V-shaped hanging strip 217, thus improving cleaning efficiency. A collection box 26 is fixedly connected to the top of the base plate 21, and an oil drain port 27 is fixedly connected to the outside of the collection box 26. A fixed plate 211 is fixedly connected to the top of the adjusting plate 210. A rotating disc 212 is rotatably connected inside the fixed plate 211. A first threaded rod 28 is fixedly connected to the top of the rotating disc 212, rotatably connected inside the fixed plate 211. The first threaded rod 28 is threadedly connected to the inside of the top plate 24. A rotating handle 29 is fixedly connected to the top of the first threaded rod 28. The elasticity of spring 216 causes the second V-shaped hanging strip 217, fixedly connected to the bottom of movable plate 215, to press against the aluminum sheet, pressing the aluminum sheet between the first V-shaped hanging strip 25 and the second V-shaped hanging strip 217. The second V-shaped hanging strip 217 guides the rolling oil on the aluminum sheet to both sides, thus cleaning the sheet and effectively removing the rolling oil. This improves the surface quality, surface roughness, and smoothness of the product, enhancing the final product's quality and appearance, and improving the adaptability and usability of the device. Fixed plate 211 has a corresponding groove on rotating plate 212. Rotating plate 212 rotates within the groove of fixed plate 211, limiting the adjustment plate 210. When the first threaded rod 28 is threadedly connected to the inside of top plate 24 for vertical adjustment, it causes the adjustment plate 210 to move up and down along with the first threaded rod 28, improving the stability of the device.
[0024] Please see Figure 1 , Figure 5In this embodiment, the adjustment assembly includes a support rod 31, which is fixedly connected to the bottom of the workbench 1. An outer frame 32 is provided at the bottom of the workbench 1. The support rod 31 is slidably connected inside the outer frame 32. A foot pad 33 is fixedly connected to the bottom of the outer frame 32. A circular hole 36 is opened inside the outer frame 32, and a second threaded rod 34 is disposed inside the circular hole 36. The second threaded rod 34 is threadedly connected to the inside of the support rod 31. A knob 35 is fixedly connected to the outside of the second threaded rod 34. A support plate 37 is fixedly connected between the outer frames 32. A hydraulic telescopic rod 38 is fixedly connected to the top of the support plate 37 and is fixedly connected to the bottom of the workbench 1. When the height of the workbench 1 needs to be adjusted, the adjustment assembly rotates the knob 35 to rotate the second threaded rod 34 out of the threaded hole of the support rod 31. By activating the hydraulic telescopic rod 38, the height of the workbench 1 is adjusted so that the threaded hole of the support rod 31 aligns with the corresponding circular hole 36, thus rotating the second threaded rod 34 out of the circular hole 36. The inner insertion mechanism, via reverse rotation of knob 35, connects the second threaded rod 34 to the threaded hole of the support rod 31, supporting the worktable 1 and improving its practicality. The outer frame 32 has a corresponding groove on the support rod 31, allowing the support rod 31 to slide within the groove, thus limiting its position and improving stability during adjustment. The support rod 31 has a corresponding threaded hole on the second threaded rod 34, which is threaded into the threaded hole. Aligning the threaded hole with the corresponding circular hole 36, rotating knob 35 causes the second threaded rod 34 to screw into the threaded hole, fixing its height and improving adaptability. Four circular holes 36 are provided, arranged sequentially from top to bottom inside the outer frame 32. Aligning the threaded hole with the corresponding circular hole, rotating knob 35 causes the second threaded rod 34 to screw into the threaded hole, fixing its height and improving adaptability.
[0025] During operation, the aluminum sheet is flattened and moved laterally by the feeding device 4 and the flattening device 6. During the lateral movement of the aluminum sheet, the precision rolling device 5 processes the aluminum sheet. The adjusting plate 210 is slidably connected to the outside of the limiting shaft 23, and the elasticity of the spring 216 causes the second V-shaped hanging strip 217 fixedly connected to the bottom of the movable plate 215 to press against the aluminum sheet, pressing the aluminum sheet between the first V-shaped hanging strip 25 and the second V-shaped hanging strip 217. The second V-shaped hanging strip 217 is used to press the rolled edge of the aluminum sheet. The oil is guided to both sides, flowing into the collection boxes 26 on both sides, and discharged through the drain port 27 to clean the aluminum sheet. When the cleaning effect on the aluminum sheet is not good, the rotating handle 29 is rotated, which drives the first threaded rod 28 to rotate. The first threaded rod 28 is threaded to the inside of the top plate 24, which drives the adjusting plate 210 to press down on the movable plate 215, thereby increasing the contact force between the second V-shaped hanging strip 217 and the aluminum sheet, thus improving the cleaning effect. When the second V-shaped hanging strip 217 and the first V-shaped hanging strip 217 are in contact with the aluminum sheet, the cleaning effect is improved. When excessive pressure between the first V-shaped hanging strip 25 causes scratches on the aluminum sheet, the movable plate 215 is lifted by rotating the handle 29 in the opposite direction. The spring 216 then presses the movable plate 215 downwards, reducing the pressure between the second V-shaped hanging strip 217 and the first V-shaped hanging strip 25. This allows for adjustment of the clamping force based on the cleaning progress of the aluminum sheet, further increasing the practicality of this invention. It prevents excessive pressure from damaging the aluminum sheet and insufficient pressure from preventing inefficient removal of rolling oil. When adjusting the height of the worktable 1, the second threaded rod 34 is unscrewed from the threaded hole of the support rod 31 by rotating the knob 35. The hydraulic telescopic rod 38 is then activated to adjust the height of the worktable 1, aligning the threaded hole of the support rod 31 with the corresponding round hole 36. The second threaded rod 34 is then inserted into the round hole 36. Rotating the knob 35 in the opposite direction connects the second threaded rod 34 to the threaded hole of the support rod 31, supporting the worktable 1 and improving its practicality.
[0026] Through the above steps, the spring 216's own elasticity causes the second V-shaped hanging strip 217, which is fixedly connected to the bottom of the movable plate 215, to press against the aluminum sheet, pressing the aluminum sheet between the first V-shaped hanging strip 25 and the second V-shaped hanging strip 217. The second V-shaped hanging strip 217 is used to guide the rolling oil on the aluminum sheet to both sides, thereby cleaning the aluminum sheet and solving the problem of rolling oil residue on the sheet, which leads to a decrease in the surface quality of the product and affects the quality and appearance of the final product.
